The M 14 is geared toward US ammo, which indeed causes no problems. But other NATO rounds, and other NATO rifles have different specs. There's the problem.
You could say much the same for the M16. Ammunition made for �other� 5.56 rifles tends to foul up an M16 pretty fast. Fortunately, the M16 has become so prolific, that most any ammo you encounter is likely meant for the M16�I guess that�s one way to solve the problem. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
But the M 16 has far less problems, according to the Speer Reloading manual, because of the gas system. And, from the same source, the M 14 is listed is problemetaical.
I've never had problems in a M 16 platfom except with exceptinoally light bullets.
